How do you do math?

When you add numbers, do you do them in your head left to right or do you do them on paper the way they taught in school, right to left?

  • I do it several different ways, depending on the problem and whether or not there is regrouping. I love math. Math is my favorite.

  • I do it in my head, but starting with the right. If it's more than a 2-digit #, I get a calculator, I hate math.

  • I love math and have always been able to visualize numbers in the air. I use my finger and calculate all kinds of mathematical equations in just plain air. I can also calculate in my head. I'm really good at math.

  • Depends on what the problem is. I hated math in school. When I was in college I had to take math for teachers of young children...that was about the easiest class there was lol

  • Pnukey and JamiDesigns- I hate you both lol.

    I usually need to write all but the simplest problems out to figure. For me, it usually only clicks if I can actually see it.

  • I can do it in my head if it's small, like no more than 2 digits and only if the two digit #s are small (like 56 + 12 I can do, but 88 + 95 I need a calculator). Anything big I need a calculator. I usually do it the way they taught us in school, it's easier for me. My son gets mad at me, though, b/c he is adding big, like 3 and 4 digit numbers, and he can't use a calculator, but I do when I check it. He always wants to know why he can't use one. I tell him I want to be sure it's wrong when I tell him it's wrong, and wouldn't he rather that than that I tell him it's wrong when he keeps getting the same answer b/c I'M wrong? That usually shuts him up. lol
